- Next Muse Spark (1.4+) released by November 30, 2026?48¢48%
- Next Muse Spark (1.4+) released by December 31, 2026?96¢96%
Meta’s recent pivot toward open-weight releases and larger frontier models has driven trader consensus to just an 8% implied probability that the next Muse Spark (1.4+) reaches the public by October 31. The closed-weight line advanced steadily with 1.1 in July, 1.2 in August, and 1.3 on September 2, delivering gains in agentic coding and tool use through the Meta Model API and Muse Code. However, the October 15 launch of Muse Spark Open—an 816B-parameter mixture-of-experts model with 1M context—plus work on codenamed successors like Watermelon has redirected resources, with no announced timelines or previews for the next incremental Spark update. Historical monthly cadence may pause amid competitive pressure from other labs and Meta’s emphasis on broader accessibility. Near-term signals such as earnings commentary or API roadmap updates could still shift odds before resolution.
Rules
This market will resolve to "Yes" if Meta's next Muse Spark model (1.4+) is made available to the general public between market creation and the specified date (ET). Otherwise, this market will resolve to "No". A qualifying model must have a name or model identifier that includes "Muse Spark" and be designated as version 1.4 or higher, regardless of capitalization, hyphenation, spacing, or surrounding prefixes, suffixes, dates, or descriptors. For example, a version 1.4 or higher named in the same manner as Muse Spark 1.2 or Muse Spark 1.3 would qualify, including a new whole-number generation such as Muse Spark 2, while models whose name does not include "Muse Spark" or which retain a version designation below 1.4, such as Muse Spark 1.3 (released September 2, 2026, including any of its reasoning modes, open-weight re-releases, rollouts, promotions, or snapshots), Muse Glimmer, or Muse Image, will not qualify. A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by Meta as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify. The primary resolution source for this market will be official information from Meta, with additional verification from a consensus of credible reporting.
